Lab Titration of Acids and Bases 5. Sodium carbonate is a reagent that may be used to standardize acids in the same way you used KHP in this experiment. In such a standardization, it was found that a 0.512 sample of sodium carbonate required 26.30 mL of a sulfuric acid solution to reach the end point for the reaction. Na CO2(aq) + H2SO (aq) →H2O(1)+ CO2(8)+ Na 50 (aq) What is the molarity of the H,SO 2 6. A solution...
8. Why is it necessary to rid the distilled water of CO,? water oorth Coz or dissolve CO2 6 Slightly because dissolued Cla react with H₂O and forms carbonic acid which more water acid So, it will effect the cading of titration experiment.- CO2(g) + H₂ Oce) H₂ CO₂ (aq) carbonic acid. > What is the molarity of a solution that contains 2.38 g of H,, 2H,0 in exactly 300 mL of solution? 10.

LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY 154 If 0,1000 M is used as the molarity of the NaOH solution in question 6, would 7 the final %Na2CO3 in the soda ash sample be greater than, less than, or equal tothetrue % Ña,соз in the soda ash sample? Failing to dry the potassium acid phthalate prior to its use would 8. a) cause the molarity of the NaOH you obtain to be greater than, less than, or equal to the true molarity...
12) 250 ml of glucose solution contains 18.016 g of solute. what is the molarity of the solution? (MW glucose 180.16 g/mol)
please help me ! H,0), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water, A chemistry student weighs out 0.279 g of citric acid ( H C He plans to titrate the acid with 0.0800 M NaOH solution. Calculate the volume of NaOH solution the student will need to add to reach the final equivalence point. Be sure your answer has the correct number of significant digits 0 mL
8) What is the molarity (M) concentration of a solution when 18.37 grams of potasslum nitrite (KNO,) is dissolved in water to make 120 mL of solution ? GENERAL CHEMISTRY LABORATORY II 9) What will the final molarity concentration of the solution in question 8 if the volume is doubled? 10) How many milliliters of 0.153 M KMnO, solution are needed to react with 6.44 grams of iron(II) sulfate in aqueous solution? The balanced reaction is: 10 Feso, + 2...
Suppose 1.00 g of NaOH is used to prepare 250 mL of an NaOH solution. Compare the expected molarity of this solution to the actual average molarity you measured in the standardization. What do you notice? Do you think the results would have been more accurate if a different type of acid or base were used in the standardization? Why, or why not? There are many different primary standards that could be used in a standardization titration. What are the...
24. How many milliliters of 2.00 M H,SO, will be required to neutralize 45.0 mL of 3.00 N KOH? 25. A careless laboratory assistant set out to determine the concentration of a perchloric acid (HCIO.) solution. He found that 50.00 mL of 1.000 N NaOH neutralized 0.5000 L of the HClO, solution. His calculations were as follows: N (50.00 mL)(1.000 N) 2 = 100.0 N HCIO, 0.5000 L Another laboratory assistant insists that the calculation is incorrect. Why? What is...
